Authorities evacuated a 24-hour cross-border flea market in Kreuzlingen and Constance early Sunday morning following a bomb threat. Police have cordoned off the port area along the banks of Lake Constance, and rail traffic between the two cities was suspended throughout the morning, according to local officials and transit reports.
Current Status of the Investigation
The investigation into the threat remains active, and authorities have not provided a timeline for when the security operation will conclude. A spokesperson for the Constance police confirmed that a bomb alert was received, prompting the immediate closure of the area. While the Thurgau cantonal police previously reported a significant intervention due to a security threat, they stated that there is no concrete danger to the general public at this time.

The flea market affected by this security operation is an annual, two-day event held simultaneously in the neighboring cities of Kreuzlingen, Switzerland, and Constance, Germany.
Operational Impacts and Public Safety
The closure of the port zone has disrupted the logistics of the annual event, which spans the border between Switzerland and Germany. Travelers and residents have been advised by Constance authorities to avoid the immediate perimeter until further notice. Rail service between the two cities was halted during the morning hours, as noted on the official CFF website.
When security threats target cross-border events, authorities must balance public safety with the logistical challenges of coordinating across two different national jurisdictions. The immediate suspension of rail traffic and the cordoning of port areas suggest a standard, high-caution response intended to secure the site before allowing normal public movement to resume.
What May Happen Next
As the investigation continues, officials may maintain the perimeter until a full sweep of the area is completed. It is likely that rail traffic between Kreuzlingen and Constance will remain suspended until police determine the site is safe. Once authorities verify the status of the threat, they may begin a phased reopening of the port area, though no official schedule for this process has been released.
